JOSEPH F. WAG-NEE, OF SOUTH BEND, INDIANA.

LAND ROLLER AND PULVER-IZEE.

Application filed April 27, 1922.

To all whom it may concern:

Be it known that I, Josnrn- F. KVAGNER, a citizen of the United States,residing at South Bend, in the county of St. Joseph and State ofIndiana, have invented certain new and usefullmprovements in LandRollers and Pulverizers, of which the following is a specification.

The invention relates to land rollers and pulverizers and has for itobject to provide a device of this character wherein a plurality ofrollers, preferably corrugated, are rotatably mounted in bearings ofyoke at the ends of the rollers, said yoke having segmentally shapedslots, the bottoms of which form bearings for bosses carried by theframe and forming means whereby the full weight of the implement will beon either roller as it passes over a clod of ground. 7 y r A furtherobject is to provide a land roller and pulverizer wherein a plurality ofrollers are used, said rollers being connected to the frame of theimplement in such a manner that when either roller passes over a clodthe entire weight of the implement will be on said roller. 7

A further object is to pivotally connect to the rear end of the framerearwardly and downwardly extending harrow tooth carrying members, whichmembers may be folded onto the frame.

A further object is to provide the frame with a forwardly extendingtongue terminating in a clevis to which draft animals or a tractor maybe attached. Also to provide a detachablehorizontally pivoted supporting truck beneath the forward end of the tongue for supporting thetongue when draft animalsare used, 7

With the above and other objects in view the invention residesin thecombination and arrangement of parts as hereinafter set roller andpulverizer, showing the harrowc attachment.

Figure 2 is a side elevation of the device showing in dotted lines theharrow carrying ieinbers folded inwardly and onto the Serial No.556,893.

frame, and showing in dotted lines the truck removed.

Figure 3 is an enlarged side elevation of the rear end of the machine,showing the forward roller on a clod of earth and the weight of theframe entirely on said roller. Figure is a view similar to Figure 3 butshowing the rear roller on a clod and of bolts dis a forwardly extendingtongue 5, to the forward end of which is secured a clevis 6 adapted tohave attached thereto in any suitable manner draft animals or a tractor.When the roller and pulverizer is drawn by draft animals a pivotedsupportin truck 7' is disposed beneath the forward end of the tongue 5and is pivotally connected thereto by means of the upwardly extendingsleeve 8, which receives a down wardly extending shaft 9. It will beseen that the truck 7 which is provided with supporting wheels 10 willsupport the tongue 5 spaced from the ground in such a manner that theweight of the tongue will not be on the draft animals. However when thedevice is drawn by a tractor and the truck 7 is removed, the weight ofthe tongue is supported by the tractor, it being understood that theclevis 6 may be attached to the tractor or if so desired the truck maybe removed and the tongue attached in any suitable manner.

Extending downwardly from the ends of the frame 1 are brackets 11, thelower ends of which are provided with outwardly tending bosses. 12 and13, the bosses 13 being in a lower horizontal plane than the bosses 12,the purpose of which will presently appear. Bosses 12 and 13 extendthrough and have slidable hearings in segmenta lly shaped slots 14 and15 of yokes 16, which yokes move in a longitudinal vertical plane as thecorrugated land rolling and pulverizing rollers 17 and 18 pass overuneven ground. The roller 17 is larger than the roller 18, however whenthe rollers are engaged with a flat surface as shown in Figure 2, thebosses 12 and 13 have hearings in the lower ends to be disposed on the11 ciency.
